Deep-ocean seaweed dumping for carbon sequestration: Questionable, risky, and not the best use of valuable biomass
- 2024
-
Ingår i: One Earth. - : Elsevier BV. - 2590-3330 .- 2590-3322. ; 7:3, s. 359-364

Tidskriftsartikel (refereegranskat)abstract
- Deep-ocean seaweed dumping is not an ecological, economical, or ethical answer to climate-change mitigation via carbon “sequestration.” Without sound science and sufficient knowledge on impacts to these fragile ecosystems, it distracts from more rational and effective blue-carbon interventions. We call for a moratorium on sinking seaweeds to deep-ocean ecosystems until its efficacy is established, and there is robust, evidence-based assessment of its environmental, economic, and societal sustainability.

Ozone-related acute excess mortality projected to increase in the absence of climate and air quality controls consistent with the Paris Agreement
- 2024

- Short-term exposure to ground-level ozone in cities is associated with increased mortality and is expected to worsen with climate and emission changes. However, no study has yet comprehensively assessed future ozone-related acute mortality across diverse geographic areas, various climate scenarios, and using CMIP6 multi-model ensembles, limiting our knowledge on future changes in global ozone-related acute mortality and our ability to design targeted health policies. Here, we combine CMIP6 simulations and epidemiological data from 406 cities in 20 countries or regions. We find that ozone-related deaths in 406 cities will increase by 45 to 6,200 deaths/year between 2010 and 2014 and between 2050 and 2054, with attributable fractions increasing in all climate scenarios (from 0.17% to 0.22% total deaths), except the single scenario consistent with the Paris Climate Agreement (declines from 0.17% to 0.15% total deaths). These findings stress the need for more stringent air quality regulations, as current standards in many countries are inadequate.

Securing Nature's Contributions to People requires at least 20%-25% (semi-)natural habitat in human-modified landscapes
- 2024

Ingår i: One Earth. - 2590-3330 .- 2590-3322. ; 7:1

Tidskriftsartikel (refereegranskat)abstract
- The cascading effects of biodiversity decline on human well-being present a pressing challenge for sustainable development. Conservation efforts often prioritize safeguarding specific species, habitats, or intact ecosystems but overlook biodiversity's fundamental role in providing Nature's Contributions to People (NCP) in human -modified landscapes. Here, we systematically review 154 peer -reviewed studies to estimate the minimum levels of (semi -)natural habitat quantity, quality, and spatial configuration needed in human -modified landscapes to secure functional integrity essential for sustaining NCP provision. We find that the provision of multiple NCP is threatened when (semi -)natural habitat in the landscape falls below an area of 20%- 25% for each km2. Five NCP almost completely disappear below a level of 10% habitat. The exact quantity, quality, and spatial configuration of habitat required depends on local context and specific NCP. Today, about two-thirds of human -modified lands have insufficient (semi -)natural habitat, requiring action for NCP regeneration. Our findings serve as a generic guideline to target conservation actions outside natural areas.

Policy documents considering biodiversity, land use, and climate in the European Arctic reveal visible, hidden, and imagined nexus approaches
- 2024
-
Ingår i: One Earth. - : Cell Press. - 2590-3330 .- 2590-3322.
-
Tidskriftsartikel (refereegranskat)abstract
- The Arctic is experiencing rapid and interlinked socio-environmental changes. Therefore, governance approaches that take the complex interactions between climate change, biodiversity loss, increasing land use pressures, and local livelihoods into account are needed: nexus approaches. However, an overview of whether and to what extent Arctic policies address these nexus elements in concert has been missing. Here we analyzed a large sample of publicly available assessment reports and policy documents from the terrestrial European Arctic. Our results show that, although nexus approaches are widely adopted in Arctic policy reporting, the emphasis varies among the governance levels, and documents underestimate certain interactions: local communities and traditional livelihoods are seldom seen as actors with agency and impact. Practical implementations were identified as potential advancements in Arctic governance: ecosystem-specific, technological, and authoritative solutions; co-production of knowledge; and adaptive co-management. Implementation of nexus approaches can promote more holistic environmental governance and guide cross-sectoral policies.

Essential environmental impact variables : A means for transparent corporate sustainabilityreporting aligned with planetary boundaries
- 2024
-
Ingår i: One Earth. - 2590-3330 .- 2590-3322. ; 7:2, s. 211-225
-
Tidskriftsartikel (refereegranskat)abstract
- Despite numerous pledges to the contrary, corporate activities are inflicting environmental harm and are pushing the Earth system toward and beyond planetary boundaries. Several sustainability accounting frameworks exist, designed to track corporate environmental impacts through corporate reporting, and there is currently a push toward standardization of these. However, most sustainability accounting frameworks still fail to fully capture the connections between corporate activities and impacts, as they depart from what is important for the companies (materiality assessments) and often rely on relative metrics. Here, we propose 15 essential environmental impact variables (EEIVs), applicable to all sectors, based on absolute metrics and what is essential for staying within the planetary boundaries. We argue that standardization must rather depart from these underlying premises. By designing EEIVs for seven primary industries with large environmental footprints and demonstrating the operationality via the aquaculture sector, we show how EEIVs efficiently identify the most important corporate impact information while increasing transparency between companies and stakeholders, thus enabling external assessment of corporate sustainability.

Hundreds of millions of people in the tropics need both wild harvests and other forms of economic development for their well-being
- 2024
-
Ingår i: One Earth. - 2590-3330 .- 2590-3322. ; 7:2, s. 311-324

Tidskriftsartikel (refereegranskat)abstract
- Local access to “wild,” common-pool terrestrial and aquatic resources is being diminished by global resource demand and large-scale conservation interventions. Many theories suggest the well-being of wild harvesters can be supported through transitions to other livelihoods, improved infrastructure, and market access. However, new theories argue that such benefits may not always occur because they are context dependent and vary across dimensions of well-being. We test these theories by comparing how wild harvesting and other livelihoods have been associated with food security and life satisfaction in different contexts across ∼10,800 households in the tropics. Wild harvests coincided with high well-being in remote, asset-poor, and less-transformed landscapes. Yet, overall, well-being increased with electrical infrastructure, proximity to cities, and household capitals. This provides large-scale confirmation of the context dependence of nature’s contributions to people, and suggests a need to maintain local wild resource access while investing in equitable access to infrastructure, markets, and skills.

Effectiveness of water-related adaptation decreases with increasing warming
- 2024
-
Ingår i: One Earth. - 2590-3330. ; 7:3, s. 444-454
-
Tidskriftsartikel (refereegranskat)abstract
- Adaptation is central to address climate impacts. At present, we have a limited understanding of the effectiveness of adaptation to reduce risks in a warming world, because adaptation remains insufficiently addressed in climate impact projections. Where projections exist, these are assessed mostly in case study settings. The importance of water is apparent within the field of climate adaptation, with the majority of documented and projected adaptation related to water. Based on a meta-review of projections of adaptation, we assess the ability of different modeled water-related adaptation options to reduce climate risk at 1.5°C, 2°C, 3°C, and 4°C of warming and show that the effectiveness of the assessed options decreases with increasing warming across all world regions and options. Although adaptation benefits can be achieved for many regions, increasing maladaptive outcomes are projected at higher levels of warming. Our analysis highlights the urgent need to limit global warming by drastically reducing emissions to avoid catastrophic impacts.
